Desktop six-axis mechanical arm for teaching

The utility model discloses a desktop six-axis mechanical arm for teaching, which comprises six main shafts capable of rotating independently, and one main shaft is driven to rotate by a stepping motor through a worm and gear transmission mechanism; the two-shaft main shaft is driven by a stepping motor to swing after being decelerated by a worm and gear speed reducer; the three-axis main shaft isdecelerated by a stepping motor through a planetary reducer and then is driven to rotate through chain transmission; the four-axis main shaft is decelerated by a stepping motor through a planetary speed reducer and then is driven to rotate through gear transmission; the five-axis main shaft is decelerated by a stepping motor through a planetary reducer, is transmitted through a bevel gear pair, and is driven to rotate through transmission of a synchronous belt; the six-axis main shaft is driven by a stepping motor to rotate after being decelerated by a planetary speed reducer; the mechanicalarm adopts various mechani
